- mchahn 8y agoI had a friend that would fix bad PCBs that had a short in a middle layer by hooking up a car battery and burning up the short. It actually worked.

- watersb 8y agoRossman (see link above) shows how to use 91% isopropyl alcohol to find these more effectively. It evaporates more rapidly at the heat source, so there's your short. I don't know how well this would work to find shorts in middle layers of circuit boards; I am still learning to identify the broken active components on the surface.
